Observation of a Charge Asymmetry in $e^+ e^- \to \mu^+ \mu^-$

The JADE collaboration
Phys.Lett. B108 (1982) 140-144, 1982

Abstract (data abstract)
DESY-PETRA. Charge asymmetry measurement in mu+ mu- events from the JADE Collaboration. More recent data are presented in BARTEL et al., ZP C26(1985)507 (& lt;a href=http://durpdg.dur.ac.uk/scripts/reacsearch.csh/TESTREAC/red+1335& gt; RED = 1335 & lt;/a& gt;).. Also see the more recent publication, Bartel et al. 1986, ZP C30, 371 (& lt;a href=http://durpdg.dur.ac.uk/scripts/reacsearch.csh/TESTREAC/red+1442& gt; RED = 1442 & lt;/a& gt;).
